Licensing on slave server

[Vidz]

Hi, i want to ask i have plan to install kaspersky  12 slave connected to my existing kaspersky 12  server, can i use same or existing license on existing master kaspersky server on slave server?

Suppose we already have license for 1000 client and used 500. 

Because when i m testing install slave server, licensing not syncronize master and slave, on slave server this license are reseting counter from 0 not from 500?

Thanks
